McMansion Hell was a hilarious website run by Kate Wagner, that skewered all the terrible, terrible designs of big American homes. It was funny but did important work. We have noted on TreeHugger that as much as 30% of heat loss can be caused by bad design, and McMansion Hell was a monument to bad design.

“[McMansions] were built to sell in the year they were selling, not for future generations,” Wagner told the Post. “These houses are kind of disfigured, because they were built from the inside out, to have the most amenities to sell faster.”

Zillow tells Gizmodo that it does not want to kill the site, but that it has "a legal obligation to enforce the agreements we make with the people who provide listings on Zillow." But many critics call this argument specious or use stronger words that we cannot publish.
